Mirtazapine is a new antidepressant with a specific pharmacological pr
ofile which is different from all other currently available antidepres
sants. It is a so-called noradrenergic and specific serotonergic antid
epressant (NaSSA). 46 in-patients were treated with mirtazapine. The m
ean dosis was 56 mg mirtazapine per day (SD: 23; range: 15 to 90). The
duration of treatment was 3.6 weeks (SD +/- 3.4). Patients presented
with following diagnosis: 29 (= 63%) were diagnosed as having a unipol
ar depression, 26% (n = 12) suffered from a depression in the course o
f a bipolar disorder. 37% (n = 17) were moderately depressed, 52% (n =
24) were severely depressed. 2 patients (= 4%) met ICD-10 (Internatio
nal Classification of Diseases) criteria for a schizoaffective disorde
r, 2 patients (= 4%) suffered from dysthymia. 1 patient suffered from
an organic depressive disorder. The efficacy of the treatment was eval
uated with CGI (Clinical Global Impression), when patients were discha
rged from hospital. 68% of the patients were in partial or full remiss
ion (CGI 2, 3 and 4), 17% were unimproved (CGI 5 and 6), in 15% of the
patients the treatment was stopped before. Our observations are indic
ative that mirtazapine is effective in the treatment of moderately and
severely depressed patients and therefore confirm the data obtained i
n phase III-trials. Furthermore we found mirtazapine in either mono- o
r combination-therapy with various other antidepressants to be tolerat
ed well. Side effects did not cause in a single patient a discontinuat
ion in treatment.
